January in Mableton is bermuda gone gold and the whole west side of town lit low and cold at seven in the morning, breath showing while the trailer gets loaded. Renteria Landscaping LLC works that quiet stretch of the calendar as seriously as June — beds cut back and cleaned out, leaves hauled off, mulch renewed, shrubs pruned while they are dormant and honest about their shape. It is unglamorous work that pays off in April, when everything comes up out of ground that was already made ready. Once the season turns, the mowing, edging and trimming take over on a steady weekly rotation. A yard tended in winter never has to be rescued in spring.
